.TOHN DE YONGH, OF NEW YORK, N. Y.

ADVERTISING-SHADE FOR INCANDESCEN'T LAMPS.

To all whom it may concern:

Be it known that I, JOHN DE YoNei-r, a citizen of the United States, residing at New York, in the borough of Manhattan and State of New York, have invented certain new and useful Improvements in Advertising-Shades for Incandescent Lamps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in lamp shades, and particularly to a shade to be fastened to the globe of an incandescent lamp.

The object of the invention is the construction of a shade which is particularly adapted for advertising purposes and which may be quickly attached to or detached from a lamp.

With this and other objects in view, the invention comprises certain novel construe tions, combinations, and arrangements of parts, as will be hereinafter fully described and claimed. 7

In the drawings :Figure 1 is a view in elevation of a shade constructed in accordance with the present invention. Fig. 2 is a view in elevation partly in section showing the shade applied to an incandescent lamp. Fig. 3 is a similar view of the lamp, the shade being shown in edge view.

Referring to the drawings by numerals, 1 designates the body of the shade and 22 tabs or extensions preferably formed integral with and on diametrically opposite parts of the body. When itis desired to secure the shade to an incandescent lamp, the globe 3 is partly unscrewed and one of the tabs or extensions 2 is inserted into the socket 4. It will be noted that the threads on the globe thus become not only the means whereby said globe is attached to the socket, but also Specification of Letters Patent.

Application filed March 26, 1906.

Serial No. 308,123.

the means whereby the shade is detachably secured within the socket. It ispreferable to employ a plurality of tabs 2 upon a shade, although the blank might be cut off at 5, Fig. 1, so as to remove the tab which is contiguous to this portion, and thereby in the present instance, leaving only one tab or extension 2 upon the shade.

The shade above described is made of paper or other suitable flexible material, and in applying the shade to the lamp one of the tabs is inserted between the threaded head of the lamp globe and the socket into which the globe is inserted, the globe being screwed into place in the socket in the usual manner. It is obvious that inasmuch as the shade is of flexible material and the inserted tab will be curved transversely when inserted into the lamp socket, the body portion of the shade will take a position substantially parallel to the central axis of the globe.

What I claim is:

1. The combination with an incandescent lamp, and its socket, of a shade consisting of thin flexible material provided with a projection detachably clamped between a screwthreaded projection of the lamp and its socket.

2. The combination with an incandescent lamp, of a screw-threaded projection, and its screw-threaded socket, of a shade composed of thin flexible material provided with a projection extending in the same plane with the body of the shade, and clamped between the screw-threaded projection of the lamp and its socket.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN DE YONGH.
